Upon installing the latest version of MobileJoomla, my entire website was gone....meaning blank white page.  I still had backend access so I disabled all modules and plugins associated and the site was back normal.

I seem to have isolated the problem to ScientiaMobile....i.e. when I activate that plugin, the site goes blank, when i disable, site comes back.

Thanks for any ideas!

Also, can I use MobileJoomla without the ScientiaMobile database?
